1/6. sepsis due to gestational psittacosis: A multidisciplinary approach within a perinatological center--review of reported cases.chlamydia psittaci is associated with significant morbidity and mortality during pregnancy, and its rarity can delay early diagnosis and treatment. A farmer's wife presented at 31 weeks with febrile illness and developed signs of septic shock, indicating immediate delivery. The child developed uneventfully. The mother survived after symptomatic mechanical ventilation, including extracorporeal lung assistance, for 11 days due to multi-organ failure. Only two weeks after admission antibody titres against chlamydia were rising. The placenta demonstrated acute intervillositis and destruction of throphoblastic cells. Retrospectively, the infection was presumed to derive from infected pregnant sheep. pregnant women should be advised to avoid contact with sheep and their gestational products. Proper history, early recognition and appropriate management is mandatory for survival of both mother and child.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
2/6. Abortion due to infection with chlamydia psittaci in a sheep farmer's wife.A farmer's wife who had helped with lambing aborted spontaneously in March after a short febrile illness in the 28th week of her pregnancy. She developed disseminated intravascular coagulation post partum with acute renal failure and pulmonary oedema. Recovery was complete after two weeks of hospital care. A strain of chlamydia psittaci, probably of ovine origin, was isolated from the placenta and fetus. The patient's serum showed rising titres of antibody against chlamydia group antigen; the placental and fetal isolates; and a known ovine abortion, but not a known avian, strain of C psittaci. IgG against both ovine abortion and enteric strains of C psittaci was detected, but IgM against only an abortion strain was detected. Histological examination showed pronounced intervillus placentitis with chlamydial inclusions in the trophoblast but no evidence of fetal infection or amnionitis. Laboratory evidence of chlamydial infection was found in an aborting ewe on the farm in January and in remaining sheep and lambs in July. Doctors should recognise the possible risk to pregnant women in rural areas where chlamydial infections in farm animals are widespread.- - - - - - - - - - ranking = 2.5keywords = sheep (Clic here for more details about this article) |
3/6. Acute placentitis and spontaneous abortion caused by chlamydia psittaci of sheep origin: a histological and ultrastructural study.A sheep farmer's wife who had been assisting with lambing developed an influenza like illness in the 28th week of pregnancy. After five days of malaise she spontaneously delivered a stillborn infant; she became acutely ill during the immediate postpartum period with septicaemic shock, acute renal failure, and disseminated intravascular coagulation. The diagnosis was made by isolation and identification of chlamydia psittaci from the placenta, fetal heart blood, and fetal lung, together with maternal serological evidence. The prominent histological and ultrastructural appearances of the chlamydial placentitis are described.- - - - - - - - - - ranking = 2.5keywords = sheep (Clic here for more details about this article) |
4/6. pregnancy complicated by psittacosis acquired from sheep.Two cases of chlamydial infection in pregnant women are described, the first serologically proved and the second suspected. In both cases the infection was probably contracted from sheep suffering with enzootic abortion. Both patients were farmers' wives who had helped their husbands and lambing and developed a non-specific febrile illness in late pregnancy. In the first case as there was no clinical improvement after 26 hours the patient was delivered by caesarean section of a live infant in good condition; the patient recovered fully. The second patient had presented a year earlier, the fetus had died in the uterus, and the patient himself died after spontaneous labour and forceps delivery 14 hours after admission. Both patients developed disseminated intravascular coagulation. As the casual agent in enzootic abortion in ewes has a predilection for the placenta, early delivery may be the management of choice in late pregnancy if infection with this organism if suspected.- - - - - - - - - - ranking = 2.5keywords = sheep (Clic here for more details about this article) |
5/6. Gestational psittacosis: case report and literature review.In europe, chlamydia psittaci is a relatively common cause of abortion in sheep and other mammals. psittacosis in humans is typically described as a mild-to-moderate flu-like illness. If psittacosis is acquired during pregnancy, it can present as a severe, progressive, febrile illness, with headache, disseminated intravascular coagulation, abnormal liver enzyme studies, and impaired renal function. Only cases with significant fetomaternal morbidity and mortality have been reported. Recovery from this disease follows termination of pregnancy and appropriate antibiotic therapy. Direct exposure of gravid humans to infected products of conception is the most commonly reported mode of transmission. Diagnosis is suggested by the placental histopathologic findings, which consist of an intense, acute intervillositis, perivillous fibrin deposition with villous necrosis, and large irregular basophilic intracytoplasmic inclusions within the syncytiotrophoblast. Commercially available genus-specific monoclonal antichlamydial antibody is available for the rapid confirmation of the diagnosis. In the united states, only two cases of gestational psittacosis have been previously reported. In contrast to the experience in europe, both cases were associated with psittacine birds. This is the first reported instance of ovine-related gestational psittacosis documented in the united states. Gravid patients should be warned to avoid contact with sheep and their products, particularly during the spring lambing period.- - - - - - - - - - ranking = 1keywords = sheep (Clic here for more details about this article) |
6/6. Gestational psittacosis in a montana sheep rancher.In humans, psittacosis is primarily a flulike illness following exposure to psittacine birds. In rare cases, pregnant women exposed to chlamydia psittaci can contract gestational psittacosis: atypical pneumonia, sepsis, and placental insufficiency resulting in premature birth or miscarriage. In the united states, only two cases of gestational psittacosis have been reported, both from exposure to psittacine birds. Eleven other cases have been reported worldwide, mostly in the United Kingdom, all from exposure to infected birth fluids and membranes of farm mammals, notably sheep and goats. In these mammals, C. psittaci inhabit the reproductive tract, are transmitted sexually or by the fecal-oral route, and cause miscarriages. The case of gestational psittacosis in a montana sheep rancher is the first farm animal-related case reported in the united states. pregnant women should avoid close contact with C. psittaci-infected animals, particularly sheep and goats during the birthing season. Obstetricians should consider this diagnosis along with early antibiotic treatment and cesarean section delivery in the context of the patient's case history.- - - - - - - - - - ranking = 3.5keywords = sheep (Clic here for more details about this article) |
